WHIFFLETREE.

SPECIFICA'IION forming part of Letters Patent N0. 410,520, da.tedSeptember 3, 1889.

Application filed Jans 5, 1889.

T0 all w7wm it may ooncern:

Be it known that I, JACOB B. HOWELL, a eitizen 0f the United States ofAmerica, residing L13 Veteran, in the county 0f Chen1ung and State 0fNew York, have invented eertain new and useful Immovements in\Vhiffietrees f01' Spring-Tooth llarrows, 0f whieh the following is aspeeification, reference, being had therein to the aecompanyingdrawings.

My imprvement in whiffierrees f01 springtooth harrows consists in itspeculiar C011- struction to enable the whiffletree t0 readily turnwithoutbeing brought into conta ct With 01 striking the harrow, and inthe peculiar strueture, combination, m1d arrangement 0f the parts,substantially as hereinafter shown and described.

In the accompanying drztwings, Figure 1 is a p1an view. Fig. 2 is aperspeetive 0f 0ne of the loops, und I ig. 3 is a side elevationthereof.

In construeting n1y whiflietree I provide the eurved easting A, ateither end thereof, with metallic 1o0ps B, secured thereto by mezms 0fnutted holte C, f01 attaching the whiffletree t0 the harrow. The eastingA is also provided at the center 01": the segment with the enlargment 01knob a, the metallie 100p Z) being secured thereto by means 0f a nuttedbolt. Loop D is in 1ike manner bolted to doub1etree h, the free ends 0fthe 100ps being Iinked Seria1 N0. 313,119, (N0 mode1.)

together by means of ring e. The loops e e and ff and the rings g g are0f similar 0011- struction and arrangement, es is obvious, and thus thedoubletree h and the singletnees F F are linked together. Thuseonstructed the harrow nmy be readily turned in very sma1l space withoutcontaet 01 striking of the parke, and a very eomplete und efficientwhiflletree is produeed.

Having thus fu1ly describetl my invention, what I elaim, und desire t0secure by Letters Patent, is

The whiflietree consisting 0f the segmentnl easting 01 P12LEG A, havingat its ends piv0ted 100ps15 B, theloop b having its ends conneeted t0 aeentra1 enlargement 01 kn0b a 0f the segmental platte A upon its re2u013 concave side, the doubletree h, having a central loop D, couneetedby a 1ing e t0 the 100p b 0f the segmenta1 plate, and the singletreesFhaving loops f, conneeted by rings g with loops e at the ends 0f thedoubletree h, substantially &S Set forth.

In testimony whereof I avtfix my signat-ure in presence of twowitnesses.
